Abstract
The invention relates to laundry detergents and cleaners comprising microdisperse, hydrophilic silicate-containing particles. The particle diameter of the particles is preferably 1 to 500 nm. The addition of the silicate-containing particles leads to improved soil release with a simultaneous reduction in the tendency for resoiling.
Claims9
A laundry detergent or cleaner which comprises microdisperse, hydrophilic silicate-containing particles having an electrically charged surface and a particle size of from 2 to 50 nm, said particles are selected from the group consisting of colloidal silica gels, colloidal silica sols, saponites and mixtures thereof said laundry detergent or cleaner comprising at least one hydrophobicizing agent selected from the group consisting of fluorosilicone oils, soil release polymers, cationic surfactants, organic fluorine compounds, and mixtures thereof.
A process for releasing soil and reducing the tendency for resoiling in laundry detergent and cleaners comprising adding to said laundry detergents and cleaners microdisperse, hydrophilic silicate-containing particles having a particle size of from 9 to 50 nm, an electrically charged surface, and said particles being selected from the group consisting of colloidal silica gels, colloidal silica sols, hectorites, saporites and mixtures thereof, said laundry detergents and cleaners comprising at least one hydrophobicizing agent selected from the group consisting of flucrosilicone oils, soil release polymers, cattonic surfactants, organic fluorine compounds, and mixtures thereof.
